Int. Cl. E06b 1/04 US. Cl. 49504 3 Claims ABSTRACT OF THE DISCLOSURE This channel sash guide structure for double-hung sliding sash windows consists of an elongated member of metal or synthetic plastic with twin longitudinal channels to the backs which are secured longitudinal backing strips of resilient foam rubber or foanpplastic which in turn are coated with a slow-drying pressure-sensitive adhesive layer covered by a protective strip of paper or other suitable sheet material. To mount the sash guide in a window frame. the workman peels off both protective strips, lines up the sash guide properly with the window frame jamb, and then presses it firmly against the jamb. This eliminates screws, drilling, alignment of screw holes, and greatly reduces the cost of labor.

In the drawings:

FIG. 1 is a rear elevation of a channel sash guide structure before mounting in a window frame, with the opposite side flanges pressed together from their normal position shown in dotted lines, and with the protective strips partly peeled off to expose the pressure-sensitive adhesive layer therebeneath;

FIG. 2 is a cross section taken along the line 2-2 in FIG. 3, with the sash guide mounted therein and mainly in rear elevation; and

FIG. 3 is a cross section taken along the line 33 in FIG. 2.

Referring to the drawings in deail, FIGS. 1 and 2 show one side structure of a conventional window frame 12 including a side jamb 14 to the opposite side edges of which are attached side members or strips 16 of greater thickness than the side jamb 14 and for that reason forming a trough 18 into which a quickly-attachable resiliently-mountable channel sash guide structure 20 is to be inserted and secured in the manner described below. It will be understood that the jamb 14 and side members or stiles 16 are ordinarily made of wood and nailed together by the carpenter in the usual way.

The channel sash guide structure 20 includes a channel sash guide 21 preferably formed of synthetic plastic material, such as polyvinyl plastic. However, it may also be made of metal. If made of plastic it is preferably formed by extrusion in which case it consists of a pair of spaced parallel channels 22 joined to one another by a bridge portion or intermediate portion 24 having beaded flanges 36 overhanging the channeds 22. The channels 22 in turn have inner and outer side wall portions 298 and 30 joined to one another by a rear wall portion 32. The outer edges of the outer side wall portions 30 are provided with inwardly-extending flanges 34 which also ex tend outward beyond the side wall portions 30 and terminate in elongated rearwardly-extending lip flanges 36 3,509,666 Patented May 5, 1970 and 38. The lip flange 36 terminates outwardly at its junction with the flange 34, whereas the lip flange 38 extends outwardly beyond its respective flange 34. It will be understod that the lip flanges 36 and 38, before mounting in the window frame 12, spring outward away from the walls or side portions 30 of the channels 22 as shown in dotted lines in FIGURE 1, so that they are mounted in the trough 1 8, they press against their respective side members 16, and thus effect a sealing engagement therewith.

Secured as by a suitable adhesive, such as a pressuresensitive adhesive layer 39, or by bonding to each of the rear wall portions 32 of the channels 22 is an elongated mounting strip 40 of resilient foam material, such as natural or synthetic foam rubber or reslient foam plastic. This in turn on its rearward or exposed side is provided with a layer 42 of a suitable slow-drying pressuresensitive adhesive. This layer 42 in turn is covered by a protective strip 44 of paper or other suitable material (FIGURE 1) which is peeled off before mounting. FIG- URE 1 shows the major portions of the protective strip 44 still in place covering the adhesive layers 42 but with their end portions 46 partly peeled off and serving as pull tabs.

In the operation of the invention, assuming that the window frame 12 has been prepared with its side members 16 nailed up to their corresponding side jambs 14, the carpenter selects one channel sash guide structure 20 as it comes from the factory with its protective strips 44 in place over the adhesive layers 42. He peels off these protective strips 44 by loosening, with his finger nails or a knife, the end portions 46 as pull tabs and thus exposes the pressure-sensitive adhesive layers 42. He then grasps the opposite side flanges 36 and 38 of the channel sash guide 20 between his thumb and fingers of his hand, and presses them inward toward one another as shown in solid lines in FIG. 1 so that they will enter the trough 18 of the side jamb 14. Thereupon he aligns and pushes the entire sash guide 20 into the trough 18 until the adhesive layer 42 adhesively engages the inner surface 48 of the jamb 14 and presses the sash guide srtucture 20 firmly thereagainst. As he does so, he releases the flanges 36 and 38, which spring outward, as a result of their resilience, into sealing engagement 'with the inner surfaces 50 of the side members 16. This completes the mounting of the sash guide structure 20 in its particular side jam b channel 18 in a quick and accurate manner and at a low cost of labor.

I claim:

1. A quickly-attachable resiliently-mountable sash guide structure adapted to be mounted in the trough of a conventional side jamb of a double-hung sash window frame, said structure comprising an elongated channel sash guide member of resilient synthetic plastic material having a pair of sash guide channel portions disposed longitudinally therealong in laterally-spaced parallel relationship with a bridge portion therebetween and having a pair of laterallyspaced elongated rectilinear attachment surfaces on the rearward sides thereof,

a pair of laterally-spaced elongated mounting strips of resilient foam material secured to said attachment surfaces each having an adhesive layer of pressuresensitive adhesive material on the exposed side thereof,

and a removable protective strip superimposed on each of said adhesive layers.

2. A quickly-attachable resiliently-mountable sash guide structure, according to claim 1, wherein the adhesive is composed of a slow-drying pressure-sensitive adhesive material.

3. A quickly-attachable resiliently-mountable sash guide structure, according to claim 1, wherein said elongated mounting strip has a second adhesive layer on its concealed side securing it to the sash guide channel portion.
